DESCRIPCIONDESCRIPTION
Metodo para producir una camara de congelacion y obtener la camara de congelacion con este metodoMethod to produce a freezing chamber and obtain the freezing chamber with this method
La presente invencion se refiere a un metodo para la produccion de una camara de congelacion, y en especial una camara de congelacion de una maquina de fabricacion de helados.The present invention relates to a method for the production of a freezing chamber, and especially a freezing chamber of an ice cream maker.
Dichas camaras estan disenadas para congelar productos alimentarios llquidos para la produccion de helados, usando un metodo de procesamiento de batido y congelacion.Said chambers are designed to freeze liquid food products for ice cream production, using a method of whipping and freezing processing.
Como se sabe, las camaras de congelacion mencionadas anteriormente consisten, sustancialmente, en un cilindro interior y un cilindro exterior que son coaxiales entre si, formando un espacio vaclo entre ellos que se extiende a lo largo de una trayectoria helicoidal para el conducto de un refrigerante.As is known, the aforementioned freezing chambers consist substantially of an inner cylinder and an outer cylinder that are coaxial with each other, forming an empty space between them that extends along a helical path for the conduit of a refrigerant. .
Un metodo conocido para la produccion de dichas camaras se describe en la patente EP 0 519 252, en la que la trayectoria helicoidal se produce enrollando un fleje de acero en una ranura helicoidal hecha sobre la superficie exterior del cilindro interior.A known method for the production of said chambers is described in EP 0 519 252, in which the helical path is produced by winding a steel strip in a helical groove made on the outer surface of the inner cylinder.
A continuacion, se fija una brida a un extremo del cilindro interior, luego el cilindro exterior se fija usando el calor y finalmente se fija una segunda brida de cierre al segundo extremo.Next, a flange is fixed to one end of the inner cylinder, then the outer cylinder is fixed using heat and finally a second closing flange is fixed to the second end.
En un segundo metodo, segun se detalla en el documento EP-0677711, con respecto a las dos bridas de extremo, la primera brida se produce por deformacion del cilindro interior por calandrado y la segunda brida de cierre para la camara se produce por deformacion del borde de extremo del cilindro exterior hasta que hace contacto con la superficie exterior del cilindro interior, donde se fija por soldadura.In a second method, as detailed in EP-0677711, with respect to the two end flanges, the first flange is produced by deformation of the inner cylinder by calendering and the second closing flange for the chamber is produced by deformation of the end edge of the outer cylinder until it makes contact with the outer surface of the inner cylinder, where it is fixed by welding.
Tales metodos conocidos implican numerosas etapas de trabajo.Such known methods involve numerous stages of work.
En el primer caso, una primera brida se situa sobre el primer cilindro y se suelda all!; el fleje de acero se enrolla alrededor del cilindro interior; all!, se fija una segunda brida de cierre.In the first case, a first flange is placed on the first cylinder and welded there !; the steel strip is wrapped around the inner cylinder; there, a second closing flange is fixed.
En el segundo caso, la brida de un extremo del cilindro interior se produce primero por deformacion de un extremo de este ultimo; el fleje de acero se enrolla alrededor del cilindro exterior; el otro extremo del cilindro exterior se deforma para obtener la segunda brida. Por lo tanto, es evidente que tales metodos requieren un tiempo de trabajo prolongado y el uso de diversas maquinas herramienta que, en consecuencia, incrementan los costes de produccion. A partir del documento WO-01/40720 se conoce un dispositivo para la produccion de hielo granulado, cuyo cilindro de congelacion puede hacerse mediante un metodo que comprende fresado y/o torneado. Por lo tanto, el objetivo de la presente invencion es el de superar los inconvenientes mencionados anteriormente mediante la produccion de una camara de congelacion que limita drasticamente el tiempo de trabajo y los costes relativos.In the second case, the flange of one end of the inner cylinder is first produced by deformation of one end of the latter; the steel strip is wrapped around the outer cylinder; the other end of the outer cylinder deforms to obtain the second flange. Therefore, it is clear that such methods require a long working time and the use of various machine tools that, consequently, increase production costs. From WO-01/40720 a device for the production of granulated ice is known, whose freezing cylinder can be made by a method comprising milling and / or turning. Therefore, the objective of the present invention is to overcome the aforementioned drawbacks by producing a freezing chamber that dramatically limits working time and relative costs.
Por consiguiente, la presente invencion alcanza dicho objetivo con un metodo para la produccion de una camara de congelacion y, en especial, una camara de congelacion de una maquina de fabricacion de helados, que tiene las caracterlsticas descritas en una o mas de las reivindicaciones del presente documento.Accordingly, the present invention achieves said objective with a method for the production of a freezing chamber and, in particular, a freezing chamber of an ice cream maker, which has the characteristics described in one or more of the claims of the present document

Como se ilustra en la Figura 2, la camara de congelacion 1 consiste en un cuerpo sustancialmente cillndrico 4, cuyo eje esta marcado con 5. El cuerpo cillndrico 4 comprende un cilindro interior 6, cuyo extremo izquierdo (visto en la figura 2), situado en una apertura 7 hecha en una pared frontal 8 de la base 3, esta sellado hermeticamente por una tapa 9 del tipo conocido.As illustrated in Figure 2, the freezing chamber 1 consists of a substantially cylindrical body 4, whose axis is marked with 5. The cylindrical body 4 comprises an inner cylinder 6, whose left end (seen in Figure 2), located in an opening 7 made in a front wall 8 of the base 3, it is hermetically sealed by a cover 9 of the known type.
La superficie cillndrica exterior 10 del cilindro interior 6 soporta una ranura en espiral 11, en la que se inserta un borde de un fleje metalico 12 sustancialmente plano.The outer cylindrical surface 10 of the inner cylinder 6 supports a spiral groove 11, into which an edge of a substantially flat metal strip 12 is inserted.
Por lo tanto, el fleje metalico 12 forma, con sus serpentines 13 que tienen un paso p constante predeterminado, una trayectoria helicoidal 14.Therefore, the metal strip 12 forms, with its coils 13 having a predetermined constant pitch p, a helical path 14.
El cuerpo cillndrico 4 comprende, ademas, un cilindro exterior 15 coaxial con el cilindro interior 6 y se monta sobre este ultimo usando el calor, para sellar hermeticamente con su superficie cillndrica interior 16 la trayectoria helicoidal 14.The cylindrical body 4 further comprises an outer cylinder 15 coaxial with the inner cylinder 6 and is mounted on the latter using heat, to hermetically seal the helical path 14 with its inner cylindrical surface 16.
El cilindro interior 6 y el cilindro exterior 15 estan unidos entre si por los extremos longitudinales respectivos por dos bridas, marcadas con 17 y 18 de izquierda a derecha. Dichas bridas 17, 18, que constituyen los elementos que cierran los dos extremos de la trayectoria helicoidal 14, consisten en una pluralidad de serpentines 13 del fleje metalico 12 que se acercan el uno al otro y se vuelven solidarios con la superficie 10 del cilindro interior 6 con las respectivas soldaduras en forma de anillo 19.The inner cylinder 6 and the outer cylinder 15 are joined together by the respective longitudinal ends by two flanges, marked 17 and 18 from left to right. Said flanges 17, 18, which constitute the elements that close the two ends of the helical path 14, consist of a plurality of coils 13 of the metal strip 12 that approach each other and become integral with the surface 10 of the inner cylinder. 6 with the respective ring-shaped welds 19.
La trayectoria helicoidal 14 constituye un circuito para el conducto de un refrigerante, cuya entrada y salida consisten en un manguito 20 y un manguito 21, respectivamente, fijados en agujeros 22 respectivos hechos en la pared del cilindro exterior 15 cerca de las bridas 17 y 18.The helical path 14 constitutes a circuit for the conduit of a refrigerant, whose inlet and outlet consist of a sleeve 20 and a sleeve 21, respectively, fixed in respective holes 22 made in the wall of the outer cylinder 15 near the flanges 17 and 18 .
Con referencia a las figuras 3 y 4 (que se refieren a realizaciones que no forman parte de la invencion), la camara de congelacion 1 se diferencia de la descrita e ilustrada en la figura 2 (que hace referencia a una realizacion que no forma parte de la invencion) en que los serpentines 13 que forman la trayectoria helicoidal 14 y las dos bridas de extremo 17 y 18 se obtienen mediante el trabajo de torneado sobre la superficie exterior 10 del cilindro interior 6, sobre la que esta montado el cilindro exterior 15 (figura 4 que hace referencia a una realizacion que no forma parte de la invencion).With reference to Figures 3 and 4 (which refer to embodiments that are not part of the invention), the freezing chamber 1 differs from that described and illustrated in Figure 2 (which refers to an embodiment that is not part of the invention) in which the coils 13 forming the helical path 14 and the two end flanges 17 and 18 are obtained by turning work on the outer surface 10 of the inner cylinder 6, on which the outer cylinder 15 is mounted (Figure 4 referring to an embodiment that is not part of the invention).
Con referencia a las figuras 5 y 6 (solo la figura 6 se refiere a una realizacion de acuerdo con la invencion) la camara de congelacion 1 difiere de la ilustrada en las figuras 3 y 4, unicamente, en que la trayectoria helicoidal 14 y las dos bridas de extremo 17 y 18 estan producidas con un trabajo de torneado sobre la superficie interior 16 del cilindro exterior 15, en el que se inserta el cilindro interior 6.With reference to figures 5 and 6 (only figure 6 refers to an embodiment according to the invention) the freezing chamber 1 differs from that illustrated in figures 3 and 4, only, in that the helical path 14 and the two end flanges 17 and 18 are produced with a turning work on the inner surface 16 of the outer cylinder 15, into which the inner cylinder 6 is inserted.
Finalmente, con referencia a la figura 7 (que se refiere a una realizacion que no forma parte de la invencion), la brida de extremo 17 se forma aplicando un elemento en forma de anillo 23 despues de la etapa de trabajo y puede fabricarse con un material plastico.Finally, with reference to Figure 7 (which refers to an embodiment that is not part of the invention), the end flange 17 is formed by applying a ring-shaped element 23 after the work stage and can be manufactured with a plastic material.
La invencion descrita presenta aplicaciones industriales evidentes y puede modificarse y adaptarse sin desviarse por ello del ambito del concepto inventivo. Ademas, todos los detalles de la invencion se pueden sustituir por elementos tecnicamente equivalentes.The described invention has obvious industrial applications and can be modified and adapted without deviating from the scope of the inventive concept.
